64 individually paid Chinese company data tools at 0.011 USDC per tool call via remote MCP and x402 on Base. 68 MCP tools total, including the schema helper and legacy tools. Selected registration, shareholder, risk, IP, legal, tax, website and other records; consult each live tool schema. Legacy Basic (3 modules) and Full (9 modules) remain 0.032 / 0.093 USDC, not bundles of the new tools. Discovery is free; data queries require a funded USDC wallet and x402 spending approval. Plain MCP clients do not pay automatically. Start with an exact Chinese legal name or company_id in company_detail; most company tools need its returned company_id. Record-detail tools use record_id from a matching separately paid parent list. New paged lists return the first page only, at most 5 rows; legacy lists at most 10. No automatic pagination, complete-history, factory or supplier-safety guarantee. Empty data is not no risk; statistics/trends are not detailed records. The old resolver is a capability notice, not a free lookup; native MPP is paused. Upstream checks passed for the 64 new tools; real-wallet payment-to-delivery acceptance and commercial redistribution/overseas delivery permission review remain pending.
